To (ZZZ whom it may concern:

Be it known that I, GUY J. EVANS, a citizen of the United tates, residing in Buffalo, in the county 01" Erie and State of New York, haveinvented new and useful Improvements in Stencils, of which the tollowing is a specification.

This invention relates to a stencil and more particularly to a stencil which comprises a plurality of sections which are connected with each other to form a longitudinal row and each of which is adapted to carry a printing or stencil sheet so that a succession of addresses or similar matter may be printed on articles to be mailed or filed.

One of the objects of this invention is to provide improved means for detachably mounting a stencil sheet on a frame so as to permit the frame to be used repeatedly with different stencil sheets and thus minimizing the expense of discarding obsolete addresses and substituting active addresses therefor.

Another object of this invention is to provide simple and elficient means for detachably connecting a series of stencil frames or sections so they form a longitudinal row and enable the same to be fed in the form of a band or chain in a printing machine which produces impressions of the stencils successively on articles to be mailed or filed and also permits each stencil to be readily replaced independently of the others in the series.

In the accompanying drawings:

Figure 1 is a perspective view of one form of stencil embodying my invention and showing aplurality of the same connected to form a band or chain. Figure 2 is a transverse section, on an enlarged scale, taken on line 2-2, Fig. 1.

Similar characters of reference ref r to like parts throughout the several views.

The form of stencil shown in Figs. 1 and 2 comprises a plurality of frame sections 10 preferably made of rectangular form in outline and of paper or other suitable material. Each of these frame sections is provided adjacent to its transverse edges with printing openings or windows 11, 12. In the assembled position of the adjacent frame sections one end of each section overlaps another section, so that the printing opening 11 in one section register with the or filed.

section. The frame sections may be connected with each other in any suitable manner but this connection is preferably of a detachable character so that the frame sections may be readily disconnected when it is desiredv to replace addressesin accordance with a re printing opening 12 in the adjacent vision of the mailing or filing list. This connection between overlappingportions of adjacent frame sections may be effected by providing each frame section at opposite ends of one of its printing openings with longitudinal coupling slots 13 and at opposite ends of its other printing openings with laterally projecting coupling lips or hooks 1 t, and engaging the lips of one frame section with slots of the overlapping part of an adjacent frame section. The material of which the frame sections are constructed should be flexible enough to permit the same to be bent sutficiently to engage and disengage the coupling lips and slots.

15 represents the stencil sheets which are adapted to extend across the printing openings of the overlapping parts of adjacent frame sections and which are adapted to receive address-perforations or like matter to be printed on the matter to be mailed Each of these stencil sheets is arranged between the overlapping parts of two adjacent frame sections and is preterably detachably connected therewith and held in place thereon by bending or folding the opposite ends 16 of the stencil sheet around the ends of the coupling lips and passing those ends through the coupling slots of the companion "frame section, whereby the stencil sheet is firmly clamped in place for use but still can be readily removed and replaced by another when revision of the mailing list becomes necessary.

The manner of securing a stencil sheet between two frame sections may also be used for holding the stencil sheet in place while taking an impression of the same regardless of whether a plurality of such stencil sections are connected to form a band or chain containing a series of perforated stencil printing sheets.

I claim as my invention:

1. A stencil comprising two frame sections arranged side by side and provided with corresponding printing openings, and one of said frame sections being provided at opposite ends of its printing openings with locking openings, and the other frame section being provided at opposite ends of its 'printing opening with locking lips which engage with said locking openings, and. a stencil sheet which is secured between said frame sections.

2. A stencil comprising two frame sections arranged side by side and provided with corresponding printing openings, and one of said frame section being provided at opposite ends of its printing opening with looking openings and the other frame section being provided at opposite ends of its printing opening with locking lips which enga e with said locking openings, and a stencll sheet which is secured between said frame sections and has its opposite ends passing around the outer ends of said lips.

3. A stencil comprising two frame sections arranged side by side and provided with corresponding printing openings, and one of said frame sections being provided at opposite ends of its printing opening with locking openings, and the other frame section being provided at opposite ends of its printing opening with locking lips which engage with said locking openings, and a stencil sheet which is secured between said frame sections and has its opposite ends passing around the outer ends of said lips and through said locking openings.
